The TPSM843A22 is a high-efficiency 18-V, 12-A synchronous buck module employing an internally compensated, fixed-frequency advanced current mode (ACM) control architecture, which while always operating under FCCM, generates output voltages from 0.5 V to 7 V. The module is capable of providing high efficiency while operating at a switching frequency up to 2.2 MHz. The module is in a 6.5-mm x 7.5-mm x 4-mm over-molded package, which makes it optimal for designs requiring a small solution size. Additional features include a high accuracy voltage reference, selectable soft-start times, monotonic start-up into prebiased outputs, selectable current limits, adjustable UVLO through the EN pin, and a full suite of fault protections.
